STMicroelectronics – HTS221

The HTS221 is an ultra compact sensor for relative humidity and temperature. It includes a sensing element and a mixed signal ASIC to provide the measurement information through digital serial interfaces.

The sensing element consists of a polymer dielectric planar capacitor structure capable of detecting relative humidity variations and is manufactured using a dedicated ST process.

The HTS221 is available in a small top-holed cap land grid array (HLGA) package guaranteed to operate over a temperature range from -40 °C to +120 °C.

  • 0 to 100% relative humidity range
  • Supply voltage: 1.7 to 3.6 V
  • Low power consumption: 2 μA @ 1 Hz ODR
  • Selectable ODR from 1 Hz to 12.5 Hz
  • High rH sensitivity: 0.004% rH/LSB
  • Humidity accuracy: ± 4.5% rH, 20 to +80% rH
  • Temperature accuracy: ± 0.5 °C,15 to +40 °C
  • Embedded 16-bit ADC
  • 16-bit humidity and temperature output data
  • SPI and I²C interfaces
  • Factory calibrated
